Four forward speeds, all-synchromesh, driven through a
9in diameter single dry plate clutch
Laycock A-type overdrive operating on third and top gears optional prior to October 1972;
standard from October 1972 to January 1973 except in certain export markets.

Laycock J-type overdrive operating on third and top gears standard from
February 1973 except in certain export markets

Note: All figures are for cars with manual transmission, except for the
Mercedes-Benz 280SL which had a four-speed automatic gearbox. The Ford was by far the
cheapest of these cars and the Mercedes-Benz was expensive enough to fall into a
completely different market sector.

It is suggested some of the following books might assist your research for your
own car, from deciding whether you want a manual or automatic, performance to
be expected, and why the Stag was designed as it is. All these books are now officially
out of print but may be available in specialist bookshops.
